Abstract
An object of the present invention is to provide a process for producing thermoplastic resin pellets, which realizes production of pellets of uniform shape. Another object of the present invention is to provide an apparatus for producing the thermoplastic resin pellets. The invention provides a process for producing thermoplastic resin pellets, including pressurizing the interior of a vessel holding a molten thermoplastic resin, thereby discharging the resin; forming pellets through solidification and cutting of the resin; and transferring the pellets to a storage container via a pipe by a pneumatic transportation or a suction transportation, wherein the amount of the resin discharged is regulated by controlling the pressure in the vessel so that variation in the difference pressure between the inlet and the outlet of the pipe for transferring the pellets is 10% or less.
